    • The Six Steps
    • When Are There Seven Steps?
    • Variables

    The number of steps in the scientific method can vary from one description to another (which mainly happens when data and analysisare separated into separate steps), however, below is a fairly standard list of the six steps you'll likely be expected to know for any science class: 1. Purpose/Question Ask a question. 2. Research Conduct background re...

    Some teach the scientific method with seven steps instead of six. In the seven-step model, the first step is to make observations. Even if you don't make observations formally, you should think about prior experiences with a subject to ask a question or solve a problem. Formal observations are a type of brainstorming that can help you find an idea ...

    When you design an experiment, you're controlling and measuring variables. There are three types of variables: 1. Controlled Variables: You can have as many controlled variables as you like. These are parts of the experiment that you try to keep constant throughout an experiment so they won't interfere with your test. Writing down controlled variab...

    • Ask a Question. The scientific method starts when you ask a question about something that you observe: How, What, When, Who, Which, Why, or Where? For a science fair project some teachers require that the question be something you can measure, preferably with a number.
    • Do Background Research. Rather than starting from scratch in putting together a plan for answering your question, you want to be a savvy scientist using library and Internet research to help you find the best way to do things and ensure that you don't repeat mistakes from the past.
    • Construct a Hypothesis. A hypothesis is an educated guess about how things work. It is an attempt to answer your question with an explanation that can be tested.
    • Test Your Hypothesis by Doing an Experiment. Your experiment tests whether your prediction is accurate and thus your hypothesis is supported or not. It is important for your experiment to be a fair test.

    • Make an Observation (Theory Construction) Every researcher starts at the very beginning. Before diving in and exploring something, one must first determine what they will study – it seems simple enough!
    • Ask a Question. Once a researcher has made observations and conducted background research, the next step is to ask a scientific question. A scientific question must be defined, testable, and measurable.
    • Form a Hypothesis (Make Predictions) A hypothesis is an educated guess about the relationship between two or more variables. A hypothesis is an attempt to answer your research question based on prior observation and background research.
    • Run an Experiment (Gather Data) The next step in the scientific method is to test your hypothesis and collect data. A researcher will design an experiment to test the hypothesis and gather data that will either support or refute the hypothesis.
